Question

I'm working on a lab and I need someone to explain how to calculate some of the data. If you could give me an example for each one I don't understand I would appreciate it more so I can work out the rest by myself. Here's my collected lab data:
Beaker # vinegar/water initial mass (g) final mass (g)
1 0 ml/35ml 120.000 122.318
2 5 ml/30 ml 120.013 122.130
3 10 ml/25 ml 120.027 122.143
4 15 ml/20ml 120.040 122.157
5 20 ml/15 ml 120.053 122.170

Answer 1

6 25 ml/10 ml 120.067 122.183
7 30 ml/ 5 ml 120.080 122.197
8 35 ml/0 ml 120.093 122.210

Answer 2

Beaker # Initial mass plus Mass of CO2 Moles of CO2 Mass of NaHCO3*
mass of AS (g) evolved (g) (moles) (g)
1 123
2 123.012
3 123.027
4 123.040
5 123.053
6 123.067
7 123.080
8 123.093

* HCO3- + HCl  H2O + CO2 + Cl-

Maximum mass of NaHCO3:

% NaHCO3 by mass:

Answer 3

Well beaker one tells you the mass of the beaker alone with nothing else I assume
So beaker 2 has 0.012 g of NaHCO3 --> convert to moles and use stoichiometry to find the amount of CO2 you produce in moles then mass i guess
